Not yet but I air tested the high pressure pump with ipr energized and had no leaks but I think I'll pull the other cover tommorow if I can't see anything else

I actually unplugged both glow plug harnesses from the gpcm. But either didn't help me at all so no sense in trying it more and hurting the engine I guess LoL

Change the oil filter every 5k miles and engine oil, fuel filters + 2 bottles of Rev-X every 10K miles.
If the root cause of failure is fixed every time they seem to stay together quite well.

Thanks that's very good to know

I was cranking and I got a po337 ckp code so I pulled out the crank sensor it looks ok but has .610K ohms of resistance that might be to high so Iam going to get a sensor from Ford tommorow.

STC fitting? Take out the icp sensor and pressurize the system with shop air to find the leak.

Icp should go to 1800 psi cranking with a healthy hpo system.
Also check rpm while cranking.

Was the surface of the block clean where the cam sensor seats? They can develop enough corrosion to move the sensor far enough out to cause a no start. Had a couple like this.

Got a amp clamp?
Remove serp belt and try to start it. Takes 2 minutes. If it starts, measure amp draw from AC compressor. Starter might be tired, you should see 200 cranking rpm to start.
